Presynaptic target of Ca2+ action on neuropeptide and acetylcholine release in Aplysia californica.


1. When buccal neuron B2 of Aplysia californica is co-cultured with sensory neurons (SNs), slow peptidergic synapses are formed. When B2 is co-cultured with neurons B3 or B6, fast cholinergic synapses are formed. 2. Patch pipettes were used to voltage clamp pre- and postsynaptic neurons and to load the caged Ca2+ chelator o-nitrophenyl EGTA (NPE) and the… (More)
